(o1. ca -49) 3 Claims.

(Grantee under the act nfMarcha- 188s-, asy amended Apn'i 30,192.8; 37o o ,-G.j757- The invention described herein maybe manufactured and used by or for the Government for governmental purposes, without thel payment to me of any royalty thereon.

The present invention relates to fastening d'evices for securing metal bands or straps on boxes,

crates and other articles. y

As is well known, bands or straps of steel or other metal are frequently passed around boxes or crates and secured thereto for the purpose o'f n 'Ihese .straps re-enforcing their construction. are usually of uniform width, and appear on the market in several sizes, usually'frornone quarter inch to two inches in width. In 'some instances these metal bands are merely applied to the box or crate to be re-enforced Without the use of lengthwise tension therein or lengthwise pulling, whereas in other instances the bands are pulled tight around the box or crate by a strapping tool which not only places tension lengthwise of the band around the box or crate but also joins the free ends of the band together by coupling means while tension still exists in the band, so that in this latter instance the band grips the box ory crate owing to the lengthwise tension.

A fastening device according to the present invention may be utilized in connection with metal band or strap applied in either of the above described manners.

Among the objects of the present 'invention is the production of a fastening device of the kind stated which may be made from sheet metal, or sheet steel, by comparatively simple blanking or cutting and bending operations.

Another object of the invention is the production of a fastening device that holds the band or strap from lateral motion or slipping and from outward motion relative to the box,'crate or other article upon which it is used, and which itself is held down by the band or strap.

Reference is now made to the accompanying drawing illustrating several embodiments of the invention. In the drawing, wherein the same characters of reference indicate the same part,

Figure 1 is a perspective View of one modiiication of the invention.

Figure 2 is a perspective View of the modification of the invention illustrated in Figure 1 before certain of the tabs have been bent into the positions shown in Figure 1, the scale of Figure 2 being greater than that of Figure 1.

Figure 3 is a plan View of a short length of steel band or strap at a position where one of the fastening devices illustrated in Figure l is applied.

Figure lis an enlarged cross section on the line 4-4 of "Figure 3 but including in section apart of the. bsx. er.. craetc i-wnhihe .fastening ,device is applied. r 1 s L vFigure is ak lerspec'tive view ci another moldicationof the invention. Y j

Figure ,6, is a perspective view of .theV modiiication of theA invention illustrated in Figure before certain of the tabs havef been bent into the positions shown ill Figure 5 f I y f 'Figure 7 is j aY perspective" view' of still' another modification 4of the fastening 'device beforecer- .tain of the tabs thereoflhave been bent. i

Figurev 8 is a perspective View of a box made of woodfboards witha steel band or' strap applied "thereto in connection with "a fastening device ments of the invention illustrated, tabs 2 have square corners at their outer ends but instead of being of this shape they may be crenated, or of the shape of isosceles trapezoids or of any other shape not presenting a sharp or snagging point at the outer end of the scallops, all of which shapes are included herein under the expression blunt or blunt scallop.

The noun tab as used herein and in the claims is intended to mean one of two or more projections arranged in a row as a border, and is not intended to be limited to any particular shape of the projection except as may be required by express terms appearing in the appended claims.

Referring to Figures 2, 6 and 7, the pointed tabs 3 are bent along the broken lines AB to a position where they are at right angles or substantially at right angles with one side; that is, the under side, of plate I. In Figures 1 and 5 the pointed tabs 3 are shown bent or turned down in the manner just described.

The pointed tabs 3 are preferably of the shape illustrated to enable them to be driven into the wood or other material of the box, crate or other article. However, these pointed tabs may be of different shape so long as they can be driven reasonably easily into the material to be penetrated by them.

pointed tabs, so long as vsuil'cient length is provided for bending over the strap or bandl5 as shown in Figures 3, 4 and 8.

In use the fastening device is driven into' the. wood 6 (see Figure 4) or other material, the band -5 placed thereover, andlthen the tab's 2 are bent inwardly over and ontothe band as shown in Figures 3, 4 and 8. In Figure 8, the form of the fastening device illustrated inl Figures 1 to 4 is l illustrated applied in two situations,- the one at the top of the box being placed at a point between the ends of the 'sl'.rap or band and the one on the side of the box'being applied over the two ends of the band to secure these free ends.

Owing to the staggered relation of the tabs 2, they can be bent overon the strap without interference of one bythe other. As will be understood from a consideration of Figures .3', 4 and 8, irregularity in the width or placement of the strap does not interfere with the use of the fastening device so long as an adequate length of tabs 2 is provided for bending over and upon strap 5. y f

It is to be noted thattabs 2 secure the band '5 against lateral displacement and that pointed scallops 3 which penetrate the body of the box, u

crate or other article to hold the fastening device in position are assisted in this action by the band or strap 5 which passes over the plate portion I of the fastening device, as shown in detail in Figures 3 and 4.

I claim:

1. A fastening device comprising a metallic plate having a plurality of tabs on each of two opposite edges, some of the tabs on each edge being pointed and others blunt, the blunt tabs on one edge being opposite the pointed tabs on the other whereby when the fastener is applied the pointed tabs and 4blunt tabs will be diagonally disposed and at right angles to each other.

2. A fastening device comprising a metallic plate having two tabs on each of two opposite I edges, one of the tabs on one edge being blunt and the other pointed, and one of the tabs on the other edge being blunt and the other Pointed,

the blunt tab on one edge being opposite the pointed tab on the other whereby when the fastener is applied the pointed tabs and blunt tabs will be diagonally disposed and at right angles to each other. v

r3. A fastening device comprising a metallic plate having three tabs on each of two opposite edges, one of the tabs on one edge being pointed and the other two blunt, and one of the tabs on the other edge being Yblunt and the other two pointed, the two blunt tabs on one edge being Vopposite the two pointed tabs on the other edge,

and thevone blunt tab on one edge being opposite the one pointed tab on the other edge.
